G. AUSTRIA BOTTLE CAP Filed April 13, 1942 Patented Sept. 14, 1943 UNlTEDSTA-TES PATENT orrlciz A texts Gnillermo'mlnlhgelmcalif. Application 1!, 1942, M NO. 438,859 5min!!- (0.51548) This invention relates to a bottle cap and more particularly pertains to a cap for encompassing the mouth of a'oonven-tional milk bottle to protectthe rim of the battle against contamination during the period between filling of the bottle at the dairy and opening thereof by the consumer.

showing the preformed cap in an inverted position in readiness for application to a bottle;

Fig. 7 is-a perspective view depicting the cap as applied.

An object of the invention is to provide a blank of thin flexible material which embodies an end or body portion adapted to be draped over the mouth and rim of a bottle and to extend around the neck portion of the latter in apron-like folds and which also embodies an integral strap portion which'is related to said body portion in an improved mannerand is adapted to be arranged to encompass the folds around the neck of the bottle and to be fastened thereto by an adhesive in such fashion as to securely retain the then formed cap in place.

A further object is to provide a formation in the blank whereby it may be folded and refolded in a series of steps such as to effect reinforcement of the strap portion thereof and also strengthen the point of interconnection of said strap portion with the main portion of the blank such as to insure against breaking of the strap or its separation from the formed cap during itsspplication to a bottle.

With the foregoing objects in view, together with such other objects and advantages as may subsequently appear, the invention resides in the parts and in the combination, construction and arrangement of parts hereinafter described and claimed, and illustrated by way of example in the accompanying drawing. in which:

Fig. 1 is a plan view of the cap blank asinltially formed;

Fig, 2 is a plan view of the blank showing it as initially folded upon itself in eilecting preformation of the blank;

Fig. 3 is a plan view of the blank shown in Fig. 2 depicting a succeeding fold operation for reinforcing the strap portion thereof; 7

Fig. 4 isa plan view of the blank as shown in Fig. 3 on a reduced scale showing the manner of forming a succeeding fold at the function of the strap portion with the mainbody portion of the blank;

Fig. 5 is a view similar to Fig. 4 showing a succeeding and final fold effected at the juncture of the strap and the body portion of the cap;

Fig. 6 is an end view of the structure shown in Fig. 5 as seen in the direction indicated by' the arrow 6 and depicting the folded portions of the body of the blank as spread apart and Referring to the drawing more specifically, A indicates generally a panel constituting the main body portion of the blank and B designates a strap formed integral with the panel A and projecting from a margin of the latter.

The panel A is substantially rectangular in form and the strap B is gradually tapered from its intersection with the portion A towards its outer end and is arrangedwith its longitudinal center extending in continuation of and in alignment with a center line extending midway between opposed edges of the panel A as indicated by the dotted line 6-0 in Fig; l-

The panel A is designed to'be positioned to extend over the mouth of a bottle and to seat on the rim of the latter with the axis of the bottle positioned at or near the center of the panel A as indicated at D in Fig 1. when so positioned the marginal portions of thepanel A will project outwardly beyond the outermargin of the mouth oi? the bottle indicated by the dotted line E in Fig. 1. The extended marginal portions ofthe panel A are designed to be turned downwardly'to overlie the outer surface of the rim of the mouth of the bottle and to extend a short distance over the bottle neck below such rim; the marginal portion of the panel being bathered and pressed into overlapping folds to substantially conform to the contour of the bottie neck. on the panel A being thus applied the strapB is wound around the bottle neck to bind the folds of the panel A into close contact with the bottle neck; the outer end portion of the vstrap'being' adhere to the underlying portion of the panel so as to securely hold the panel in its cap formation on the bottle; the outer end por tion of the strap having adhesive B applied thereto for this purpose.

In order to reinforce the strap B at its intersection with the panel A, fillets F are provided at the intersections of the margins of the strap B with the contiguous margins of the panel A and in order to eliminate an unsightly and unnecessary buckling of the marginal portion of the panel A at the juncture of the strap and anel when the latter is applied, the corners of the panel contiguous the nllets F are roundedas indicated at G and H and the corner H and its associated fillet F is set back or cut away relative to the comer E and its associated fillet F.

In preforming the blank shown in Fig. 1 it is appear as shown in Fig. 2 with the marginal 5 portions thereof embodying a rounded-corner G projecting slightly beyond its opposite margin embodying the rounded corner H. The extended margin K of the strap B is then bent on a.

diagonally extending fold line L-L providing a tapered flap M which with the underlying fold N of the strap B forms the outer end portion of the latter with three plies of the sheet material and thus greatly increasing the strength of the and the invention embraces such changes, modifications and equivalents of the parts and their formation and arrangement as come; within the purview of the appended claims. 1

I claim:

v l. A bottle cap comprising a panel !and an integral strap extending from an edge thereof, said panel and strap being formed of thin sheet flexible material and being folded longitudinally of the latter, and said strap having an edge thereof'foldedto overlie-the first named fold, 'andbeing twisted at its juncture with the panel.

2. Thestructure called for in claim 1 in which the panel is formed with marginal fillets mergouter portion of the strap. The strap is then ing into the edges of said strap at the inner porbent upwardly along a diagonal fold 0-0 at the juncture of the strap with the fillets F so that v the strap will then extend in oblique relation to the fold JJ as shown in Fig. 3. The strap l is then again folded along the line.PP intersecting theflllets F so as to extend at an obtuse angle relative to the fold line J-J as shown in Fig. 5. The folds along the line 00 and P-P impart a twist in the material at the juncture of the strap with the panel. On this being done, as

the overlying side portions of the panel are spread apart as shown in Fig. 6, whereupon the panel is in readiness for positioning over the mouth of the bottle as before described; When so initiallypositioned, the strap 13 will extend so 7 angular relation to the folded panel.

tangentially to the periphery of the bottle neck 'as indicated by the broken lines Q in Fig. '7 and v whereby the strap is dlrectioned for winding circumferentially around 'the'bottle neck in overlying relation to the crimped folds of the 'marginal portion of the panel A. On attaching the outer end of the strap B to the underlying portion of the panel A as by means of the adhesive B, the resultant formed cap, will be securely held in place on the bottle so as to afrord a prm 4 tective sheath'for the rim of the bottle month end in a fashion to prevent such rim beingoontaminated from sources external 0! the bottle.

on severingv e strap the cap maybe removed.

While I have shown and described a specific 4 \tion thereof.

3. -A bottle cap comprising a rectangular panel and an integral strap extending from an end of "said panel intermediate the edges thereof, said panel and strap being formed of thin sheet flexible material, said panel having marginal fillets merging into the edges of said strap, one of said fillets being oflset relative to the other; said panel and strap being folded longitudinally of the latter to one side of the longitudinal center thereof whereby one fold is offset in overlying relation to the other, said strap having its protruding edge portion folded relative to its previously folded edge, and said strap being twisted at its inner end portion to extend in flexible sheet material, and a thin flexible strap Joined to and extending from said panel and twisted at its juncture with the panel whenthe latter and the strap are applied as a closure for abottle.
